deriveRememberKey
Signature
function deriveRememberKey(string memory mnemonic, uint32 index) internal returns (address who, uint256 privateKey)
Description
Derive a private key from a mnemonic and also store it in forge’s local wallet. Returns the address and private key.
Example
Get a private key and address from the test mnemonic at path m/44'/60'/0'/0/0. Use them to sign some data and start broadcasting transactions:
string memory mnemonic = "test test test test test test test test test test test junk";
(address deployer, uint256 privateKey) = deriveRememberKey(mnemonic, 0);
bytes32 hash = keccak256("Signed by deployer");
(uint8 v, bytes32 r, bytes32 s) = vm.sign(privateKey, hash);
vm.startBroadcast(deployer);
...
vm.stopBroadcast();
